I am still curious about the massive shifts in CHR, Hot AC, and AC at the turn of the 2010s. I remember things like Lady Gaga, Kesha, and Taio Cruz being big on CHR and then gradually crossing over to Hot AC and even AC. Were the testing for that through the roof? I remember rock bands like Daughtry and The Fray diminishing during this time. It seems like nothing like this has happened since and there haven't been any massive shifts since then, but was curious what was going on then?
